ABSTRACT:
An apparatus for embossing a flexible substrate with an optically transparent compliant media is disclosed. The complaint media includes an optically transparent imprint stamp with an imprint pattern therein. The flexible substrate is coated with a photopolymer material. The compliant media can be connected with an optically transparent belt material to form an embossing belt or connected with an optically transparent cylinder to from an embossing drum. A coated side of the flexible substrate is urged into contact with the imprint stamp and the imprint pattern is embossed in the photopolymer material and an ultraviolet light passing through the compliant media contemporaneously cures the photopolymer material during the embossing.
